1 All movement in the body is the result of muscle contraction without exception. 2  True False. 3  In addition to movement, muscle contraction also fulfills some other important functions in the body, such as posture, joint stability, and heat production. 4  True False.
Biodiversity is important because certain organisms have economic value (such as rainforest plants being made into medicine), they have value to the ecosystem (think of their spot on a food web), and they are a source of natural beauty and recreation.iodiversity is important because humans d â¦ epend on animals and other species to live and grow and much as animals and other species depend on humans to live and grow. It's important because it is based on the evolution of other species.
Soil organisms are responsible, to a varying degree depending on the system, for performing vital functions in the soil. Soil organisms make up the diversity of life in the soil (Figure A1.1). This soil biodiversity is an important but poorly understood component of terrestrial ecosystems.he rhizosphere is the region of soil immediately adjacent to and affected by plant roots. It is a very dynamic environment where plants, soil, micro-organisms, nutrients and water meet and interact. The rhizosphere differs from the bulk soil because of the activities of plant roots and their effect on soil organisms.
